He who mocks the infant’s faith
Shall be mocked in age and death.
He who shall teach the child to doubt
The rotting grave shall ne’er get out.
He who respects the infant’s faith
Triumphs over hell and death.
The child’s toys and the old man’s reasons
Are the fruits of the two seasons.
The questioner who sits so sly
Shall never know how to reply.
He who replies to words of doubt
Doth put the light of knowledge out.
The strongest poison ever known
Came from Caesar’s laurel crown.
Nought can deform the human race
Like to the armour’s iron brace.
When gold and gems adorn the plough
To peaceful arts shall Envy bow.
A riddle or the cricket’s cry
Is to doubt a fit reply.
The emmet’s inch and eagle’s mile
Make lame philosophy to smile.
He who doubts from what he sees
Will ne’er believe, do what you please.
If the sun and moon should doubt,
They’d immediately go out.

William Blake

Blake wasn’t a man of faith, but of vision. St. Paul didn’t start preaching until he had a vision. Then he preached his experience in terms of faith to the inexperienced. Blake Elk had a vision. Jacob Boehme had a vision. One can have faith in Mohammad. I’ve had faith in my lawyer. The Catholics who introduced genocide into Christian Europe during the Albigensian crusade had faith. Moses saw a burning bush and had a vision. Luther had faith, threw an ink bottle at the devil, gave up on the Jews, and late in life persecuted them. Best be careful of what we have faith in, and be able to distinguish a vision from a phantasy.
